Correct Answer: A

Rationale: The correct answer is A because reassessing the client's diet, medication, and lifestyle habits allows the nurse to identify any factors contributing to the elevated blood glucose levels. By identifying possible issues, the nurse can make necessary adjustments to the treatment plan to better manage the client's condition. Increasing medication dosage without understanding the root cause may lead to adverse effects. Simply documenting the elevated levels without taking proactive measures does not address the problem. Notifying the client's family is not the nurse's first action; the focus should be on assessing and addressing the client's needs.

Correct Answer: C

Rationale: The nurse interprets this as respiratory alkalosis because the patient is likely experiencing hyperventilation, leading to a decrease in CO2 levels and respiratory alkalosis. This is indicated by an increase in pH and a decrease in PaCO2 on arterial blood gas analysis. Metabolic acidosis (choice B) is characterized by low pH and low bicarbonate levels, not seen in this scenario. Respiratory acidosis (choice A) is characterized by high PaCO2 levels and low pH, which is not the case here. Metabolic alkalosis (choice D) is characterized by high pH and high bicarbonate levels, which is not consistent with the patient's presentation.

Correct Answer: D

Rationale: Correct Answer: D - Lubricating eye drops Rationale: Lubricating eye drops help prevent complications such as corneal abrasions in patients with Bell's Palsy by keeping the eye moist and preventing dryness. Bell's Palsy can cause difficulty in closing the eye properly, leading to dryness and potential damage to the cornea. Using lubricating eye drops helps maintain eye health. Summary of Incorrect Choices: A: Megavitamin therapy - Not directly related to preventing complications in Bell's Palsy. B: Application of ice to the affected area - Ice may not address eye dryness or prevent corneal abrasions. C: Elastic bandages - Not relevant to preventing complications associated with Bell's Palsy.

Correct Answer: C

Rationale: The correct answer is C. Hormonal imbalances are the primary cause of BPH in aging males. As men age, testosterone levels decrease and estrogen levels may increase relative to testosterone, leading to prostate gland growth. This is why hormonal imbalances are more likely the cause of BPH in older males. Explanation of other choices: A: Chronic infection of the urinary tract does not directly cause BPH, although it can lead to similar symptoms such as urinary frequency and urgency. B: Chronic cigarette smoking is not a direct cause of BPH, although it can contribute to overall prostate health and exacerbate symptoms. D: Chronic obstruction of the bladder due to stone is a separate condition from BPH, although it can cause similar urinary symptoms.

Correct Answer: A

Rationale: The correct answer is A: Anemia. Anemia is a common condition characterized by a decrease in red blood cells or hemoglobin levels, leading to symptoms like fatigue and weakness. It is often suspected based on symptoms such as pale skin and shortness of breath. Rheumatic arthritis (B) is a type of arthritis affecting joints, not related to the blood. Leukemia (C) is a type of cancer affecting the blood and bone marrow. Systemic Lupus Erythematosus (SLE) (D) is an autoimmune disease that can affect various organs, not specifically related to blood cell levels. Therefore, based on the symptoms described, anemia is the most likely condition to be suspected.
